QoS policy groups

You can use System Manager to create, edit, and delete QoS policy groups.

More information

Creating QoS policy groups
You can use System Manager to create storage Quality of Service (QoS) policy groups to limit the throughput of workloads and to monitor workload performance.

Deleting QoS policy groups
You can use System Manager to delete a Storage Quality of Service (QoS) policy group that is no longer required.

Editing QoS policy groups
You can use the Edit Policy Group dialog box in System Manager to modify the name and maximum throughput of an existing storage Quality of Service (QoS) policy group.

Managing workload performance by using Storage QoS
Storage Quality of Service (QoS) can help you manage risks around meeting your performance objectives. You can use Storage QoS to limit the throughput to workloads and to monitor workload performance. You can reactively limit workloads to address performance problems, and you can proactively limit workloads to prevent performance problems.

How Storage QoS works
Storage QoS controls workloads that are assigned to policy groups by throttling and prioritizing client operations (SAN and NAS data requests) and system operations.

How the maximum throughput limit works
You can specify one service-level objective for a Storage QoS policy group: a maximum throughput limit. A maximum throughput limit, which you define in terms of IOPS, MBps, or both, specifies the throughput that the workloads in the policy group cannot collectively exceed.

QoS Policy Groups window
Storage QoS (Quality of Service) can help you manage risks related to meeting your performance objectives. Storage QoS enables you to limit the throughput of workloads and to monitor workload performance. You can use the QoS Policy groups window to manage your policy groups and view information about them.
